Diffusive transport in a quasiperiodic Fibonacci chain: absence of many-body localization at small interactions
Vipin Kerala Varma, Marko Znidaric
We study high-temperature magnetization transport in a many-body spin-1/2 chain with on-site quasiperiodic potential governed by the Fibonacci rule. In the absence of interactions…

Length scales in the many-body localized phase and their spectral signatures
Vipin Kerala Varma, Abhishek Raj, Sarang Gopalakrishnan +2
We compute and compare the decay lengths of several correlation functions and effective coupling constants in the many-body localized (MBL) phase. To this end, we consider the dist…
